Many thanks for working on this feature and making it happen.  I tested
it briefly and no problems until now.  I have one question though
reg. activation of AUCTeX modes now.

One issue pointed out by users is/was that AUCTeX takes over the
standard LaTeX mode once installed; this can be circumvented by setting
`TeX-modes' accordingly.  Now people can also set
`major-mode-remap-alist', and I suspect with something like this:

  (setq major-mode-remap-alist '((latex-mode . latex-mode))

If so, should we document this more prominently, maybe under 1.2.4
Loading the package[1]?  And then loading AUCTeX LaTeX mode is done with
'M-x LaTeX-mode RET'?

Again, many thanks for working on this.

Best, Arash
